Facial Electromyography (fEMG)

January 30, 2020

fEMG is used to measure which facial muscles are being contracted, by measuring the underlying electrical activity of one or more sets of activated muscles (under contraction). In doing so, it helps to understand the expressed emotion on an individual’s face. fEMG is typically a more sensitive measure than FACS, but it does require the use of sensors and cables, whereas FACS only requires a trained observer or camera.
